Similar here. Fixed for 1year in 05/06. They turned my wife and i away saying we were to early to discuss options. We defaulted as we've learned in the last couple of years due to an error as to where they were sending letters.
My wife and i received all our information back from the bank and we found letters we never got and also didnt see any copies of letters we sent in.
We never got an options letter or notice of any kind we were about to default.
In the information we had recieved, there was a reply letter stating we would ( or should have been, ) offered a tracker at some point but never we never got that. We were offered an apology.
My wife knows the details in and out. And were going to court. Our solicitor believes we have a case, so we'll take it.
If you had issues with the bank and have letters asking questions or made a complaint it may be worth getting your mortgage information to see if theres holes in their story.
It's a big undertaking, but if you know something is wrong its at least worth a look.
If I recall correctly the deadline has passed, so your likely to be going against the current. I didnt get any help here myself.
You may well be on your own.
